When using the Raster -> Analysis -> Grid (Inverse Distance to a Power)
At the menu just before pressing run, can somebody please explain me the effect of the "Weighting power" option in the interpolation process? I'm trying to make a temperature map based on points representing each weather station, containing the yearly averages values of temperature, and when moving the number from the 2 (set it by default) to 4, 6 or 10, the map changes significantly
